I ANDREW now, or SEATTL WASHINGTbN- srUM-P-rUrJLER;

saw -N 1 To all whom it'mdg concern: i citizen ofthe United States, residing atSeattle,

in the countyoftKing and State of Wash ington, have invented certain new and use-.

4 ful, Improvements in. Stump-Pullers, of

which the following is a specification.

. This invention relates to. portable windlasses and is designed,'n1ore especially for use as a'stump puller. Y 2 i y A The object of my invention is the provision of an inexpensively constructed, durable, powerful and efficient machine of this character. I y

. The invention consists in the novel construction, adaptation and combination of part'sas hereinafter described and claimed.

In the accompanying drawings, l

Figure 1 is a plannview;shownpartly broken away, of. a'machi-ne. embodying the present invention. Fig. 21s a detail elevational view of the cable attaching arm at the left hand side of Fig. 1 as viewed from line 2.-2 of the same. Figs. 3 and 4 are sectional views through 3-3 and 44 of Fig. 1. Fig. 5 is a sectionalview through 5-5 of Fig. 4. Fig. 6 is a plan view of the machine shown applied.

In carrying out my invention, I provide aframe comprising a base plate 10 provided with apertured lugs 11 for bolts 12 whereby the frame is .secured to a supporting beam 13. Extending upwardly from said base plate and integral therewith is a flange of substantially the shape in which it is shown in Fig. 1that is to say, with a portion 15 which is an arc of a circle arranged concentric to the center of the base plate.

Another portion 16of said flange extends inwardly to accommodate a spur pinion 17 Rotatable mounted upon the outer periph cry of the flange part 15 is a; cable winding drum 18 having in its inner periphery a series of spur teeth 19 which engage the aforesaid spur pinion. Said pinion is formed integral with or rigidly connected to an arbor20 which is journaled in bearings 21 and 22 respectively provided in the frame base 10 and a cover-plate 23 which is removably secured to said base anclupon the flange thereof as by means of bolts 24.

Secured to the arbor 20 above said frame is aratchet wheel 25 which is intermittently actuated through the medium of a spring pressed pawl 26 connected to a pivot Specification of Letters Patent.

Pivotallyconnected to one of said boltsv2 4 isadog 32 which is engageable with the teeth 19 of the drum to prevent accidental retrograde movements of the latter. s 1 j Said dOgdsrendered operable bymeans of-a spring:33, connecting the dog to the arm 3410f a lever which is fulcrumed at 35 inthe frame cover. plate andis' provided above-suchplate with an arm- 34 whereby the arm 34 may beswung from its dotted line position, Fig." 1,.against a ,stud 36. to a positionagainst asecond stud86 *By thus moving said lever, the spring33' is brought from its illustrated position whereat it acts to yieldingly retain the dog 32 in engaged relations with the drum teeth into a position whereat the spring serves to retain the dog away from the drum teeth when it is desired to release the drum for takingup slack in the cable or unwinding thesame from the drum.

-Tl16 base plate 10 of the machine frame is provided with oppositely extending axially alined arm elements 38 and 39 provided with eyes 38 and 39 Referring to Fig. 6,40 represents an anattached to a stump 46 being pulled, and

said hauling cable extends by a lead 44 thereofthrough a guide element 46 protruding from the frame arm 39 and is wound as at 44 Fig. 4, in a number ofturns about the drum. The tangential positions of the 7 arms 38 and 39 with respect to the drum at f its connection with the operating pinion therefor are important features of the present invention, the same beingarranged so that the cable strains will be applied in a line extending medially of'the engagement between the pinion and the drum. By such devices the drum is subjected to but small strains or stresses, and the drum is rotated with practically no torsional strains and With a minimum of friction upon the bearing therefor. a 7

After the cables are connected tothe machine, to the anchor object and to a stump which is to be drawn from the ground, as aboveexplained, the machine is operated by actuating the bar 31 as Willbe understood.

What I claim, is,

1.- 'In amachin'e of the-ch-araeter described,

drum, a pinion having an arbor journaled in said frame and engaging-themlrumiteeth, an operating bar,-opera'tive connections ibetween said barhand the pinionfor transmitting intermittent rotary motion to said drum, and; a springxactuated dog for progressively engaging the drum teeth during the rotation of the drum.

2. In' a machine @of the character described, the combinationof a frame comprising a base plate having an upwardly extending flange portion, and a cover plate secured upon the latter, said base plate being provided at its opposite sides with axially alined arms, a cable Winding drum rotatably mounted upon said flange and provided Wit 1 internal gear teeth, ag pinion engaging said 'drum teeth, an arbor for said pinion journa-led in said framebaseand covermembers, a ratchet Wheel mounted upon said a-rbor, a pawl for said Wheel, an operating bEtI, 3J

head therefor journaled upon said airbor and carrying said pawl for imparting intermittentrotary motion to said-ratchet Wheel 7 whereby the pinion is actuated to drive said drum, apul leygadapte'd to becon'nec'tedte a stump, a hauling cable ,passing about the sheave of said pulley, anend oifsaid :e'abl'e being connected to one of said arms-and the other end oi the cable being wound about 1 said drum, and an a nchor cable reonnected to the other of sand arms. a
